Abstract
本发明公开了一种质量流量控制器的检测诊断方法及系统。该方法包括：连续采集质量流量控制器的流量测量时间序列、阀门控制参数和电源参数；基于阀门控制参数和电源参数对当前时刻流量进行多参数估计得到第一虚拟流量，并基于历史流量测量值和历史流量设定值对当前时刻流量进行时序预测得到第二虚拟流量；分别计算当前流量测量值与第一虚拟流量的第一偏差、与第二虚拟流量的第二偏差；当第一偏差或第二偏差超过预设阈值时，将两个偏差的数值组合与预设故障特征库进行模式匹配，输出故障诊断结果。本申请通过双路径虚拟流量验证和故障特征匹配，实现了质量流量控制器检测数据与故障类型的智能关联诊断，提升了设备运维效率和故障诊断准确性。
